Automatically restarting ZPyGreSQLDA connection
by Hannu Krosing 01 Jun '99

01 Jun '99

Hi, Is there any way to catch the error from a Zope Database Adapter and restart it ? I'm experiencing what I suspect are timeout problems (sometimes a bunch of imapd's drive the load to >10 and make the computer really slow). The symptom is that at some point I get a traceback from _pgmodule instead of nice page. The only way to fix it after that is going to manage screens and shutdown/startup the connection I would like to catch this exception and do the shutdown/startup automatically (and perhaps log that it happened) Or would the only reasonable place to do such things be inside the DA ? The latter should not be too hard, just try: to send an empty query before the real one (con.query("")) and in except: open a new one (and log the error if desired) The overhead should be almost nothing, at least when using domain sockets. --------------- Hannu

What happens is this: DTML is pre-parsed, and all the DTML tags are replaced by object instances representing those tags. The attributes are stored as instance variables. This means that 'sortby' is evaluated only once, when you save the DTML code. Right now there is no real solution to your problem, other then creating different #in tags and selecting one with an if - elseif - else structure. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

sysv init script for Zope 2
by Alex Rice 01 Jun '99

01 Jun '99

Here is an init script for Zope2/ZServer. Folks might find it useful just as a wrapper around z2.py. That's how I'm using it. On Redhat Linux, the init scripts are kind of covoluted-- I'm still not sure how it handles killing daemons. If you are comfortable with Redhat's init scripts, try putting a symlink to this script in /etc/rc.d/rc5.d/. #!/bin/sh # # Init script for the Zope2 application server (using ZServer) # # Alex Rice <alex(a)mindlube.com> # notes: # o don't put this in /etc/rc.d/rcX.d/ unless you know what you are doing # o format copied from other Redhat 6 init scripts # o make sure your network interface is up before you start zope! # adjust these as appropriate ZOPE_BASE=/usr/share/zope PYTHON=/usr/local/bin/python # there better way to get DNS server (like from /etc/resolv.conf) anyways... # put your DNS server here: NS=127.0.0.1 # See how we were called. case "$1" in start) echo -n "Starting Zope: " $PYTHON $ZOPE_BASE/z2.py -d $NS & echo ;; stop) echo -n "Shutting down zope: " $PYTHON $ZOPE_BASE/lib/python/ZPublisher/Client.py \ -u ` cat $ZOPE_BASE/access ` \ http://localhost:9673/Control_Panel/manage_shutdown \ > /dev/null 2>&1 echo ;; status) echo "Status of Zope: " echo "<this feature not yet implemented>" ;; restart) echo -n "Restarting zope: " $PYTHON $ZOPE_BASE/lib/python/ZPublisher/Client.py \ -u ` cat $ZOPE_BASE/access ` \ http://localhost:9673/Control_Panel/manage_restart echo ;; reload) echo -n "Reloading zope: " $PYTHON $ZOPE_BASE/lib/python/ZPublisher/Client.py \ -u ` cat $ZOPE_BASE/access ` \ http://localhost:9673/Control_Panel/manage_restart echo ;; *) echo "Usage: $0 {start|stop|restart|reload|status}" exit 1 esac exit 0

If you use python 1.5.1 with 1.11.0pr1 like DC tells you too, and 1.5.2 with 2.0.0a1, you'll indeed notice a difference.

If so, this shouldn't be happening. If you are using 2.0.0, I believe this bug has been fixed and you should definatly downgrade to 1.10.2, which is our latest stable release. If you are using 1.10.2, we should look into this. Can you give us some more platform details? OS? Python? Zope? -Michel PS Zap is a bit outdated, although it is known to work with 1.10.2. > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Of course, you could define a Property of the top-level folder called (for example) pDistantLogo and then use <IMG SRC=""> or something. --Rob

Re: [Zope] Printable Page
by Kevin Dangoor 31 May '99

Hi, I don't think there is exactly a HOW-TO on this, but every page on the Zope site has a DTML Source link that shows you how the page works. The printable pages link is actually pretty straightforward. http://www.zope.org/dtml_source?path=/standard_html_header shows you the standard_html_header used on the Zope site. Within this method, you'll see ... So, the all the printable page link does is set the pp variable when it calls the DTML Method. Then, standard_html_header will print just the small header instead of the full header. The dtml_source method on the zope site can be a really useful tool.

server says "document contains no data"
by Stefan Thull 31 May '99

31 May '99

Hi after long experimenting I finally succeeded in installing Zope with Zap as webserver. :-))) As I tried to go through the Quicktutorial I got a strange error. As I tried to add a new DTML Document from the main menu it took a long long time and finally it ended with the (netscape-)error: Document contains no data The same thing happened as I tried to add an image or a document from a file. Does anybody know where the problem is? Thank you stefan Thull
